What does this PR do?

Adds a native /goal command that enables multi-turn autonomous goal execution, similar to Codex CLI's /goal command. Feature gated behind experimental.goals config flag (default off).

Implementation approach:

The goal runtime is backed by a new GoalTable in SQLite (via existing Drizzle ORM). A SessionGoal.Service state machine handles CRUD, token budget tracking, and iteration limits. Two model tools (create_goal, update_goal) let the model manage goals autonomously.

The key design challenge was avoiding InstanceRef not provided errors — config.get() needs InstanceRef which isn't available during layer resolution. The fix: SessionGoal.Service and config.get() are accessed lazily inside runLoop (after outcome === "break"), not at the layer effect level.

Goal continuation works by injecting a synthetic user message with a continuation prompt when the goal is still active after a turn. The loop continues automatically until the goal is marked complete or the iteration limit (default 50) is reached.

/goal command registration is conditional on cfg.experimental?.goals === true.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Introduces an experimental “goals” capability that lets a session persist an objective, continue autonomously across turns, and update goal status via new tools and a /goal command.

Changes:

Added goal session storage + service layer and wired it into the app/runtime layers.
Introduced create_goal / update_goal tools and a new /goal command template.
Extended the session prompt loop to optionally auto-continue when a goal is active.

Add a native /goal command that enables multi-turn autonomous goal execution, matching the implementation approach of Codex CLI. Key changes: - New GoalTable schema (thread_id PK, objective, status, token budget, iteration count) and GoalStatus union type in session.sql.ts - Goal runtime state machine in session/goal.ts with CRUD operations, continuation prompt generation, budget tracking, and iteration limits - create_goal and update_goal model tools in tool/goal.ts, with SessionGoal.Service resolved lazily inside execute (not at define time) - Goal tools registered unconditionally in tool/registry.ts, feature gated only at runtime via experimental.goals config check - /goal command registered in command/index.ts behind experimental.goals feature flag - Goal continuation logic in prompt.ts runLoop: after outcome is 'break', checks for active goal and injects continuation prompt as a synthetic user message before continuing the loop - SessionGoal.defaultLayer merged into AppLayer in app-runtime.ts - Goal event types (GoalSet, GoalUpdated, GoalCleared, GoalCompleted) in session-event.ts with no-op handlers in session-message-updater.ts Fixes anomalyco#27162

Hi @adamdotdevin, all Copilot review comments have been addressed. I have also added additional features on top: get_goal tool, /goal pause|resume|clear subcommands, --token-budget <N> argument support, and wall-clock time tracking. Typecheck is clean and all relevant tests pass. PR description has been updated. Would appreciate a re-review when you get a chance. Thanks!

NathanKong76 · 2026-05-23T02:32:45Z

Quick update: I found and fixed a critical missing piece — the database migration for the goal table was never generated. Without it, the feature would crash on first use with "no such table: goal". I also wrote 16 E2E tests covering the entire SessionGoal.Service (set, get, clear, pause, resume, accountUsage, incrementIteration, budget enforcement, continuation prompts, status transitions). All tests pass. The branch is now up-to-date with dev.
